Abstract:
An output discharge circuit for a load switch may include a capacitor coupled between a power rail of the output discharge circuit and a ground lead, and a diode coupled between a power input of the output discharge circuit and the power rail. The output discharge circuit may charge the capacitor via a current path formed by the diode while power is being supplied to the load switch. When the power supply to the output discharge circuit is turned off, the diode may prevent the capacitor from discharging through the current path, and the stored charge on the capacitor may be used to power the output discharge switch for a period of time after the power supply has been turned off. In this way, the output discharge circuit may continue to discharge the output of the load switch even when power is no longer being supplied to the load switch.
